Abstract: The correct procedures for drawing inferences about the population as a whole from knowledge provided by a sample form the major part of the branch of statistics known as inferential statistics. The first step in making an inference about a population from a sample is the calculation of the descriptive statistics of the sample itself. Inferential statistics is built upon descriptive statistics. The corresponding magnitudes in the population as a whole are known as parameters. In inferential statistics, one infers from the statistics of samples to the corresponding parameters of the population. If a population parameter is to be estimated from a sample statistic, there are three factors that must be taken into account. The first is the method by which the sample is chosen, the second is the size of the sample, and the third is the degree of confidence that can be placed in the estimate.
